To all whom it may concern,.-

Beit known that I, AnoLrn F. BECKER, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Electric Fans, of which the following isa specificatiomreference being had therein to the accompanying drawings. i

This invention relates to an improvement in that class of propeller-fans which are designed for use either as desk or wall fans and it has for its object to rovide a simple and effective construction ofP universal connection between the motor frame and standard, whereby such members may be made to assume the desired relations without the manipulation of any fastening means, such as clamp-screws and other fastening devices.

Theinvention consists, primarily, in afan of the class described having one of its relatively shiftable members provided with a bearingball, and the other with a bearing therefor having opposed spring pressed clamping members, Wherebythe bearing. thus formed not only maintains the ball member in fixed relation to the socket member, but imposes upon the former suicient friction to resist the gravity of the frame when in inclined position.

The invention further includes certain de tails of construction herein shown and described.

In the drawings annexed, Figurel is an elevation of a fan embodying the present improvement,'illustrating the same in full lines adjusted for use as a desk-fan and showing the base member in dotted lines when adjusted for attachment to a side wall? Fig. 2 is a sectional elevation, upon an enlarged scale, illustrating the constructive features of the universal bearing connecting the two fan members, and Fig. 3 is a sectional plan showing in section the shank by which the bearingball is attached to the motor-frame.

The motor member comprises the propellerwheel a, carried by the motor-shaft b, journaled in the motor-frame c, from the lower side of which projects the rigid shank d, terminating in the bearing-ball c.

The base member or standard comprises the base f, provided in its upper portion with threaded boss g, to which is fitted the internally-threaded hub h of the socket-piece '11,

being interposed betweenthe top of theV threaded hub g and the lower si e of the thrust-ring for forcin the latter constanty against the bearing-ba l e, and thereby yiel ingly clamping the same between itself and the rigid member of the socket-bearing.

As indicated in dotted lines in Fig. 2, the shank d is tubular in form,.and the ball e is formed with an axial connecting-passage i, terminating in a slot 'i5 upon one side of its lower portion, whereby the usual flexible conducting-wires t or cables may bc led from the motor-frame downwardly through the shank d, ball e, thrust-ring j, and spring c into the hollow hub g and base f, to the usual switch,

which latter is not shown herein, as it forms no part of the present invention. By the em loyment of a complete spherical knob or ball)e I am enabled to secure a uniform bearing-surface for the ball-joint whatever the position which the motor-frame c is caused to assume, thereby insuring the effective operation of the motor-frame support under all conditions, the lateral slot '1,5 providing for the direct lead of the conducting cor or cable from the motor to the base f in any adj ustment of the fan.

From the foregoing description it will be observed that in turning the motor-frame` upon its base it is merely necessary to overcome the frictional resistance im osed by the spring-socket bearin upon the all e, while by the provision of t e socket-piece t' with a lateral slot i3 extending downwardly below the center of curvature of the socket end the base member may be turned up at a right angle to the shank d for attachment of the structure to a side wail, or the two principal members of the fan may be adjusted at any intermediate angle to give the required direction to the air-current produced by operation of the same.
